Hi @Danny2121,
Can you kindly check if you are use TeamViewer Full client please? It would usually show the password below TeamViewer ID
At the same time, kindly your TeamViewer settings too,
TeamViewer - GearWheel ⚙ (top right upper corner) - Security - Random password - Password strength
Let me know if any of the information above will be helpful in your case.
Best,
Ying_Q
